. TELEGRAPH-POLE.

Specification of Letters Patent. Patented Jam. 17, 1911.

Application filed October 25, 1909. Serial No. 524,447.

To all whom it may concern:

Be it known that I, Josnrir H. Norrrow, a citizen of the United States. residing at Mullinville, in the county of Kiowa and Slot-e of Kansas, have invented certain new and useful Improvements in Tllclegraph- Poles, of which the following is a specifica tion.

This invention relates to concrete posts, to which insulators may be conveniently at tached.

. An object of the invention is to construct a telegraph pole or the like which will withstand usage and conditions to which it is liable to greater advantage than the poles of like nature which are employed at the present time, and to provide a pole which may be readily erected and upon which may be placed any desired number of conductors.

The invention has for another object the provision of a device of this character which is of simple construction, is of great strength and which may be easily and economically manufactured.

Other objects and advantages will be apparent from the following description and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit: of the inven tion.

In the drawings forming a portion of I this specification,- and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a front elevation of the device. Fig. 2 is a side elevation of the same, Fig. a longitudinal section through the standard, Fig. 4t is a detailed sectional view of one of the cross arms employed in, connection with the, device, Fig.

I 5 is a section on the line S 5 of Fig. 1, Fig.

t3 a section on the line 6-3 of F 1, Fig. 7 is a detailed sectional low of the connection between the standard and the lower cross arm, Fig. 8 is a detail perspective View of a portion of the reinforcing standard.

Referring to the drawings, 10 designates a base of circular formation upon the upper face of which are secured three vertically disposed rods 11, which are equi-distant from each other and indicate the vertices of aftriangle. These rods are slightly convergent at their upper extremities. The rods 11 are held in position by means of the horizontally disposed braces 12 and are sorods 2 cured further by means of the diagonally disposed bars 13 which are positioned between the braces 12 at their extremities where the same are fastened to-the rods 11. The rods 1]. arc-also provided with laterally extended steps 14 which are oppositely disposed in staggered relation upon the same and which aresecured thereto by means of the depending flanges 15 formed upon the inner extremities of the steps 14 which are 'rivoted to the outer faces of the rods 11.

The upper extremity of the standard, which is formed by the rods 11, is provided with a circular plate 16 which extends slightly beyond theouter edges of the rods 11 and which serve to hold a concrete casing 17 which is disposedupon the base 10 and extended upwardly about the rods 11 and engaged against the lower face of the plate '16- The braces 12- and bars 13 also serve the purpose of reinforcing the concrete casing 17 and of holding the same in position.

At the up )er extremity of the standard and at one side thereof, the casing 17 is provided with a semi-circular notch 17 to admit of the positioning of an upper cross arm 18 which is positioned against and across two of the rods 11 upon the outer faces thereof and secured in such position by means of bolts '19 and 90 which extend through the cross arm 18 between the. rods 11 and are engaged at their opposite extremities in a clamping plate 21. The clamping plate 21 engages the outer face of the remaining rod 11 and is positioned in parallel with the cross arm 18 and serves to securely hold the cross arin rigidly in position. arm 18 comprises metallic bars 22 and 23 which are held in parallel relation by means of the braces 24 positioned between the same and which are reinforced by thediagonally dis osed arms 25 which are en a ed betweenthe bars 22 and 23 and pass the central portions of the braces 24. Between and about the bars 2:2 and 23 is positioned a concrete filling 96 which serves the purpose of pro tecting the bars 22 and 23 and the adjoining members disposed upon the same. The bars 22 and 23 are provided with a plurality of equidistantly spaced and vertically disposed which are detachably engaged therethrough and which are secured in position by clamping nuts 28 which. admit of the extension of the rods 27 beyond the same. These rods are threaded and insulators 29 are adapted to be engaged therewith upon which are secured the electrical conductors. v body portion composed of cement, braces dis- For the purpose of further supporting the upper cross arm 18 the lower bars 23 are provided with depending ears between which are pivotally secured the brace arms 31 which extend downwardly and inwardly where they are engaged with outwardly extended lugs 32 carried by the rods 11. The brace arms 31 are also provided with insulator rods 33 which are horizontally positioncd through the same upon which are adapted to be secured additional conductors.

At the upper end of the standard, at a distance slightly below the upper cross arm 18, is positioned a second cross arm 34 which is of similar construction to the upper cross arm 18 but which is slightly elongated for the purpose of admitting of the protruding of the outer extremities of the same beyond the ends of the cross arm 18. The cross arm 34 is provided with a plurality of insulator rods 35 which are vertically disposed through the same, having their threaded portions alternately arranged to extend upwardly and downwardly from the cross arm. The cross arm 34 is also provided with brace arms 36 which are secured to lugs 37 extended laterally from the rods 11 and en- 4 gaged at their upper diverged extremities to the depended ears 38 carried upon the under side of the cross arm 34. At the point of contact where the cross arm 34 is secured to the standard, the concrete casin 17 is transversely recessed to admit of t e positioning of the cross arm 34 against the rods 11 and to admit of the securing of the same in such position, by means of the bolts 39 which are secured through the cross arm 34 and through a plate 40 disposed across the opposite side of the rods 11 for rigidly securin the cross arm 34 in such position. For the purpose of protecting the'pole and the several parts of the same, a lightning rod 41 is positioned down one side of the concrete casing 17 and is held in such position b 1 means of cleats 42 embedded in the concrete casing a distance outward of the rods 11. The lightning rod 41 is carried to the groundin the usual manner and is extended centrally over the standard for the purpose of protecting the cross arms 18 and 34.

When the device is to be employed the standard isfirst erected and the cross arms 18 and 34 are. then positioned as the casing 17 is so molded as to form a cutaway portion to admit of the. positioning of the cross arms and the lugse32 and 37 are projected beyond the sides of the casing 17 to secure the bra ce arms 31 and 36 after the cross arms 18 and-'34 have been properly positioned.
